According to Keirsey's
temperaments, I am a "Rational"
personality type - i.e., a "knowledge-seeking personality". The other three main Keirsey's personality types are
Artisans, Guardians, and Idealists. My personality is
consistent with the "Mastermind" sub-type - or an INTJ personality in Jungian terminology. INTJ stands for Introverted, iNtuitive, Thinking, Judging.

The INTJ, "knowledge-seeking personality type"
apparently is somewhat rare (less than 1%
occurrence). INTJs tend to exhibit a combination of imagination and
practicality. "Rationals" generally make good scientifists,
sometimes as
inventors, sometimes as organizers of knowledge. INTJs tend to
hang in the background, vociferously imagining, analysing and organizing
information. However, the INTJ is self-confident and will
step up to lead when he/she feels it is appropriate (i.e., when he/she has enough knowledge and
there is a need).

I am a knowledge-broker, motivated by learning,
teaching and research. If you combine
the INTJ personality type with high optimism,
strong valuing of nature-based life styles physical fitness, somewhat left wing
political views, and a devilish sense of humor, you have some idea about
who I am.
